Abstract
A refrigerator has an air sanitation device. The air sanitation device includes: a housing; an air channel located in the housing and having an air inlet and an air outlet; a fan located in the air channel, to force air to enter the air channel from the air inlet, and then be discharged out of the air channel from the air outlet; and an air detection device and/or an air purification device located between the air inlet and an inlet of the fan.
Claims13
An air sanitation device for a refrigerator, comprising:
- a housing;
- an air channel disposed in said housing and having an air inlet and an air outlet;
- a fan disposed in said air channel to force air to enter said air channel from said air inlet, and then be discharged out of said air channel from said air outlet, said fan having an inlet;
- an air detection device disposed between said air inlet and said inlet of said fan, wherein said air detection device has a circuit board and a gas sensor fixed to said circuit board;
- said air channel is configured to enable the air to flow along a side of said circuit board to which said gas sensor is fixed;
- and
- a direction that said inlet (41) of said fan (4) faces is opposite to a direction in which said gas sensor protrudes from said circuit board.
